Abstract
A method of operating a communications device to perform cell reselection in a wireless communications network, the method comprising establishing a radio resource control (RRC) connection, suspending the RRC connection, transmitting a first message in a first cell, the message comprising a request that the RRC connection be resumed, before the RRC connection is resumed the first cell, selecting as a serving cell a second cell different from the first cell, and transmitting a second message in the second cell, the second message comprising a request that the RRC connection be resumed.
Claims18
A method of operating a communications device to perform cell reselection in a wireless communications network, the method comprising
- establishing a radio resource control, RRC, connection,
- suspending the RRC connection,
- transmitting a first message in a first cell, the message comprising a request that the RRC connection be resumed,
- before the RRC connection is resumed in the first cell, selecting as a serving cell a second cell different from the first cell, and
- transmitting in the second cell a request that the RRC connection be resumed.
A method of operating a communications device to perform cell reselection in a wireless communications network, the method comprising
- establishing a radio resource control, RRC, connection,
- suspending the RRC connection,
- determining a radio access network-based (RAN-based) notification area (RNA), the RNA comprising a plurality of cells within which the communications device is not required to notify the wireless communications network of a cell reselection;
- selecting as a serving cell a first cell, the first cell not being within the RNA,
- transmitting a first message in the first cell, the message comprising a request that the RRC connection be resumed,
- before the RRC connection is resumed in the first cell, selecting as the serving cell a second cell different from the first cell, and
- transmitting in the second cell an RNA update indication indicating that the cell selected as the serving cell of the communications device is not within the RNA.
A method of operating an infrastructure equipment in a wireless communications network, the method comprising
- transmitting an enhanced resume procedure indicator that indicates that a communications device is permitted to transmit an RNA update notification after a cell reselection procedure to a current serving cell which occurred prior to a completion of an RRC resume procedure in a previous serving cell.
A method of operating an infrastructure equipment in a wireless communications network, the method comprising
- transmitting an indicator which indicates that a communications device is permitted to request that an RRC connection be resumed after a cell reselection procedure to a current serving cell which occurred prior to a completion of an RRC resume procedure in a previous serving cell.
